If the discriminant, b^2 — 4ac is positive (or > 0), then the solution will be two (2) distinct real solutions.
If the discriminant is positive ( > 0), there are 2 real solutions.
If the discriminant is = 0, there is 1 real repeated solution.
If the discriminant is negative (< 0), there are 2 complex solutions (but no real solutions).
Answer:
True
Step-by-step explanation:
"Positions to the left of the origin are negative. Distance is the absolute value of the displacement. Distance is always positive and tells how far something is from something else but does not tell us whether it is to the right or to the left."
Answer:
126.5
Step-by-step explanation:
Divide the shape into two, so you have a triangle and a rectangle.
Area of Rectangle:
A = bh
= (11)(8)
= 88
Area of Triangle:
A = 1/2bh
= 1/2(11)(7)
= 38.5
Add the two areas and the answer is 126.5
G+f=100liters
$1g + $1.5f = $130
g=130-1.5f substitute into first equation for g
(130-1.5f)+f=100
130-.5f=100
-.5f=100-130
-.5f=-30
f=-30/-.5
f= 60 liters of fruit juice
substitute into first equation
g+60 = 100liters
g=100-60
g=40 liters of ginger ale
Put x = 1
y = 12 (1)
y = 12
so x = 1
y = 12
put x = -1
y = 12 (-1)
y = -12
so x = -1
y = -12
Your correct options are A and C.
